We look at the division of 21727866 by 702 
The aim is to understand the frequency of 702 in 21727866.

Let's proceed to step 1:
2 divided by 702 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 702

Advancing to step 2:
702 can be fit into 21 0 times, resulting in a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 702

Advancing to step 3:
When dividing 217 by 702, we get 0 with a remainder of 217.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 217, we get 217.
Include the next digit (2) from the dividend after 217, then repeat: 2172 / 702

Going ahead to step 4:
702 goes into 2172 3 times with a remainder of 66.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 2106 from 2172 and we're left with 66.
Bring next digit (7) of the dividend behind the 66 and repeat the process: 667 / 702

Advancing to step 5:
667 divided by 702 is 0 with a remainder of 667.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
The remainder is 667 after subtracting 0 from 667.
Bring next digit (8) of the dividend behind the 667 and repeat the process: 6678 / 702

Going ahead to step 6:
6678 divided by 702 is 9 with a remainder of 360.
Put 9 as the next digit of the answer. 
Result so far: 309.0
Deduct 6318 from 6678 and we're left with 360.
Include the next digit (6) from the dividend after 360, then repeat: 3606 / 702

Moving on to step 7:
If we divide 3606 by 702, we get 5 and a remainder of 96.
Use 5 as the next digit of our solution. 
Result so far: 3095.0
Subtract 3510 from 3606 to get 96.
Take the next digit (6) from the dividend and append it to 96, then repeat: 966 / 702

Advancing to step 8:
966 divided by 702 is 1 with a remainder of 264.
Write down 1 as next digit of the result. 
Result so far: 30951.0
Subtract 702 from 966 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Advancing to step 9:
When dividing 2640 by 702, we get 3 with a remainder of 534.
Put 3 as the next digit of the answer. 
Result so far: 30951.3
The remainder is 534 after subtracting 2106 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Moving on to step 10:
When dividing 5340 by 702, we get 7 with a remainder of 426.
Record the quotient 7 as the next digit in the result. 
Result so far: 30951.37
If we take 4914 away from 5340, we end up with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Advancing to step 11:
4260 divided by 702 is 6 with a remainder of 48.
The next digit of our result is 6. 
Result so far: 30951.376
The remainder is 48 after subtracting 4212 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 12:
702 goes into 480 0 times with a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 30951.376
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 13:
702 can be fit into 4800 6 times, resulting in a remainder of 588.
Use 6 as the next digit of our solution. 
Result so far: 30951.37606
Subtracting 4212 from 4800 leaves us with 588.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5880, and continue the process.

Moving on to step 14:
When dividing 5880 by 702, we get 8 with a remainder of 264.
The next digit of our result is 8. 
Result so far: 30951.376068
Subtract 5616 from 5880 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Let's proceed to step 15:
If we divide 2640 by 702, we get 3 and a remainder of 534.
Put 3 as the next digit of the answer. 
Result so far: 30951.3760683
Subtract 2106 from 2640 to get 534.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5340, and continue the process.

Step 16:
If we divide 5340 by 702, we get 7 and a remainder of 426.
The next digit of our result is 7. 
Result so far: 30951.37606837
The remainder is 426 after subtracting 4914 from 5340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

The final result is 30951.37606837 with a remainder of 4.26e-07.
